Game Idea

The goal of my game is for the cat to eat the mice. Each level of my game will get harder. There will be about 3 or 4 levels. The levels can get harder by the mice going faster, or enemies meaning if you get those things you lose points, or there could possibly even be a time limit and a goal of how many mice you need to eat. Level 1 will take place in a desert, level 2 will take place in a hay field, and level 3 will take place in on a hill. The levels will get harder as it goes on.
